DC handheld resistance tester

DC handheld resistance tester

Model KM OHM 8502

Handheld DC resistance tester, also known as transformer DC resistance tester, DC resistance fast tester, ground continuity tester, adopts microprocessor technology, four-wire method for testing, safe, precise and reliable. Mainly used to measure the resistance of transformer windings, transformer winding resistance, grounding down conductor continuity test, cable wire resistance, switches, connectors, contact resistance of relays, coils, motors, and equipment casings, lightning protection belts, and ground Connection resistance test between metal components of beams, structures, cabinets, steel bars, water pipes, windows, guardrails, radiators, assembly lines and other objects. It is widely used in telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, etc.

Handheld DC resistance tester is composed of a host, monitoring software, test lines, communication lines, etc. The handheld and portable design of the host is convenient for on-site application, with charging function, no need to find electricity on site, full-color large-screen LCD display, clear at a glance, convenient and easy to use touch screen operation, and port overload prevention function. Large-capacity storage of 500 sets of data, resistance measurement range : 10.0mΩ-50.00KΩ, measurement accuracy : 0.2%. The upper computer software has functions such as historical data reading, consulting, saving, and reporting.
